When using Aluminum Electrolytic Capacitors, please observe the following points to ensure optimum capacitor performance and long life.

1>DC electrolytic capacitors are polarized.

Make sure of the polarity which is marked on the body of the capacitor.  
Application of the reversed voltage may cause a short circuit or damage to the capacitor.  
Use bipolar capacitors when the polarity is not determined or unknown.  
Note that DC electrolytic capacitors CAN NOT be used for AC application.

2>Bipolar capacitors
These capacitors are used only in pulse circuits as well as polarity reverse circuits, but not applicable in pure AC or high ripple current. 

3>Do not apply voltage greater than the rated voltage
If a voltage exceeding the rated voltage is applied, the leakage current will increase, which will damage the capacitor.  
Recommended working voltage is 70% - 80% of rated voltage.  
Using capacitors at recommended working voltage prolongs capacitor life.

4>Do not allow excessive ripple current through the capacitor
The flow of ripple current greater than the permissible (rated) value will cause heating of the capacitor, which may decrease the capacitance and damage the capacitor.
Ripple current through the capacitor must be at or below the allowable level, generally not more than 80% of the rated current.

5>Use specially designed capacitors for the circuits where charge and discharge are frequently repeated.
In circuits subjected to rapid charge and discharge cycles, a capacitor may be damaged and its life may be shortened by capacitance decrease at higher temperature.  

6. Operating temperature range.

The characteristics of capacitors change with the operating temperature.  
The capacitance and leakage current increase and dissipation factor will decrease at higher temperatures. Usage at lower temperature will ensure longer life.

7. Temperature vs. Life.

The expected life of a capacitor is related to its ambient temperature. 
Generally, if the ambient temperature is reduced 10℃, life is doubled at rated voltage. 

8. Check operating frequency.

Electrolytes usually have their capacitance measured at 100 Hz. or 120 Hz.  
However, remember that capacitance decreases and dissipation factor increase as the applied frequency becomes higher.

9. Capacitor Storage

Long periods of storage have virtually no effect on a capacitor’s capacitance and dissipation factor. 
However, such periods can increase leakage current and decrease the capacitors withstand voltage. 
Apply rated DC voltage treatment to the capacitors which have been stored for a long time.

10. The capacitor case is not insulated from the cathode terminal.

The capacitor’s case and cathode terminal connect through the electrolyte. 
If the case is to be completely insulated, that insulation must be at the capacitor’s mounting point.

11. Do not apply excessive force to the terminals and leads.

An excessively strong force applied to the terminals and lead wires may cause leads to break or terminals to separate and, in turn, cause the internal contact to fail.

12. Cleaning of the circuit board after solder dipping.

Clean circuit boards to remove flux or other extraneous matter.  
To ensure protection for the sleeve, its marking, and the capacitor's sealing materials, the capacitor should never be washed or cleaned by halogenous agents or solvents such as trichlorethylene, xylene, acetone, etc. 
Recommended cleaning solvents; Methanol, isopropanol ethanol, isobutene, petroleum ether, propanol and/ or commercial detergents.

13. Be cautious of the temperature and duration when soldering.
Soldering irons should be kept away from vinyl-insulated sleeves of capacitor.  
When the capacitor is dipped in a solder bath, use at less than 260℃ and 10 seconds to avoid damaging the capacitor.

14. Hole positions on the circuit board.
When designing a circuit board, space the through-holes equal to the space between the capacitor's lead wires. 
If the spacing is either greater than or less than the capacitor's leads, mounting will apply stress to the leads, causing short circuits, broken circuits, and increased current.
Also, through-holes on the circuit board as well as lead holes of post-process parts can result in solder splashing onto the vinyl sleeve causing damage.  
Consider hole positions carefully.

Featurette and the story behind

1. With regard to investment
In order to produce a satisfactory film, Wu still mortgaged the house to the bank, Wu interview said: "Although a lot of investors are willing to give money, but there will be a lot of additional requirements, in order to do not want to film by investors too much interference, and finally mortgage the house to the bank, loans 80 million.

2. About actress
When the actress was chosen, Wu wanted to find a domestic famous actor, turn no, he said, (the domestic actress to find a like him to fight the same do not double, and even singing also want doubles, this is the current situation in the line!) So just choose the Lu Jingxian, starred in the Spike, really good, people from childhood martial arts, father was also an action actor, compared to some domestic actress, Lujen do very well.

3. About underwater fighting scenes
The film starts with a mirror of the underwater fight, which requires him to stay underwater for about three and a half minutes, just this one nearly 6 minutes of the long shot, Wu took a whole big half a month, 25 consecutive diving attempt, the last 26th time Wu feel the best, several times the suffocation, this dedication and dedication, is very worthy of affirmation.

4. About the hospital shootout
It's dangerous to shoot a gunfight in a hospital. Because the hospital's residential area itself has a lot of militants, this is the real armed elements are not the kind of film, according to Wu's introduction, before filming to find a lot of local people to protect security, should also give local militants some costs. This does not specify that all staff members should not act alone or go outside the film when filming, because there may be a real AK47 to give you a burst of hair at any time.

5. About Guest Accidents
This video Wu see props group too careless to guest's African girl hurt, very angry video Wu said dirty words, really is said you he horse what all ignore, the text did not play out, only play you all ignore.
But I was touched when I saw this video. Also very shaking, feel scold good, should do so, a good director of a responsible director should cherish and care for everyone in the crew, even if it is a small group of little play after the Wu personally hands-on help little girl wrapped wound and protective gear.

6. About Mr. Wu Gang
During the filming, Wu Gang teacher accidentally hit the plate, leading to the waist injury, can not move in order not to delay the filming progress, he simply after the treatment on the film to continue filming, by eating stop pain tablets quite, Wu gang teacher said, when you challenge yourself is no hesitation, this dedication to the Director Wu deeply admire.
Imagine if this role were to be given to a domestic actor who even had to be a stand-in for the singing to do what it would have done, and to think of it as a deep tribute to all the good actors in professional love.

Aluminum Electrolytic Capacitor, simply called Eelectrolytic Capacitor (e-cap), is a type of capacitor that uses electrolyte to achieve larger capacitance than other capacitor types. It consists of cathode aluminum foil, electrolytic paper, electrolyte, and aluminum oxide film, which acts as the dielectric, formed on the anode foil surface.

Due to its large capacitance, Aluminum Electrolytic Capacitor is suitable for passing or bypassing low frequency signals and storing large amounts of energy. It widely be used in power supplies and for decoupling unwanted AC components from DC power connections.
